INDIAN INSTITUTE OF TECHNOLOGY GANDHINAGAR Department of Civil Engineering Soil Mechanics Laboratory UNCONSOLIDATED UNDRAINED TRIAXIAL COMPRESSION (UU) TEST (IS Part ) Reaffirmed THEORY: 1. A loading frame in which the load is applied by yoke acting through an elastic dynamometer, more Estimated Reading Time: 2 mins. 1. Before testing, adjust the measuring range according to the capacity of the test piece. 2. Hold the test specimen driving chuck with the help of handles. 3. Adjust the angle measuring dial at zero position, block pointer at the starting position and pen its required position. 4. Bring the red dummy pointer in the line with black pointer. 5.

Vickers Hardness Test 31 Rockwell Hardness Tests 35 Tests on Wood Compression Test on Wood 37 A compression test can be performed on UTM by keeping the test-piece on base block (see in fig.) and moving down the central grip to apply load. It can also be performed on a compression testing machine. A compression testing machine shown in fig. it has two compression plates/heads. The upper head moveable while the lower head is stationary. 2. This strength is determined by conduct of a compression test. Compression test is just opposite in nature to tensile test. Nature of deformation and fracture is quite different from that in tensile test. Compressive load tends to squeeze the specimen. Brittle materials are generally weak in tension but strong in compression. Hence this test is normally performed on cast iron, cement concrete etc.

This experiment provides fundamental knowledge on compression behaviour of materials specially wood/timber, test procedure, universal testing machine and. Unconfined Compression TEST lab manual · Note down the sample number, bore-hole number and the depth at which the sample was taken. · Take about 10 to 15 g of. With the above objective in mind, each experiment in the manual is divided into three Tests for determination of compressive strength of concrete
